Dayco PB1165N harmonic balancer for the 1998-2010 Subaru Forester and other vehicles damps crankshaft vibration. The Dayco harmonic balancer mounts on the crankshaft and turns the serpentine belt.
Visible cracks, a loose-looking outer ring, engine vibration or belt noise can mean the engine harmonic balancer is worn. A tired serpentine belt or tensioner can produce some of the same symptoms, so track down the actual cause before you buy.
This harmonic balancer is a direct-fit replacement for the 1998-2010 Subaru Forester, the 1998-2014 Subaru Impreza and the 2000-2009 Subaru Outback. The 1998-2010 Subaru Forester takes one. If your car isn't named here, look up its year and engine on the Buyer's Guide tab.
